Hi patriot1. It wasn't my idea, but, I agree, it is a clever application. Since I don't have any decent program on my pc with the dvd burner, I just use MS Paint. Pathetic, but it works. My still images are not fancy.
You don't have to put the still images in any particular folder. When you select that option under Compression Settings in DVD Shrink, you can browse for your picture. I also just checked my other pc and saw that there was a link to the dvd shrink website for more pics.
The still image will last for however long your movie is. I made a mistake in my last post, I said you could edit the length of the still image but you can't do this in "full disc" mode, only in "reauthor".
